glsl: add ARB_shading_language_include support to #line

From the ARB_shading_language_include spec:

   "#line must have, after macro substitution, one of the following
    forms:

       #line <line>
       #line <line> <source-string-number>
       #line <line> "<path>"

    where <line> and <source-string-number> are constant integer
    expressions and <path> is a valid string for a path supplied in the
    #include directive. After processing this directive (including its
    new-line), the implementation will behave as if it is compiling at
    line number <line> and source string number <source-string-number>
    or <path> path. Subsequent source strings will be numbered

etnaviv: blt: set TS dirty after clear

RS engine does this already, it is missing for BLT engine. This fixes
cases where a clear isn't immediately at the start of the frame.

etnaviv: separate PE and RS formats, use only RS only for tiling

There are PE formats not supported by RS, so we can't have a single
to translate both.

Use RS only for same formats until we have a translate_rs_format and test
the possible different format blits.

etnaviv: blt: use only for tiling, and add missing formats

* Removes the incorrect usage of translate_rs_format
* Disables use of BLT engine for different src/dst format

We only really need the BLT engine for tiling/detiling right now, but it
would be nice to support as many blit cases as possible to avoid using PE
for that.

To deal with different formats we need to:
 * Have a translate_blt_format which has all supported formats
 * Fix the swizzle translation from gallium (current version was wrong)
 * Set the src/dst sRGB bits as needed
 * Find which type conversions the BLT engine can actually do

Call shmget() with permission 0600 instead of 0777

A security advisory (TALOS-2019-0857/CVE-2019-5068) found that
creating shared memory regions with permission mode 0777 could allow
any user to access that memory.  Several Mesa drivers use shared-
memory XImages to implement back buffers for improved performance.

This path changes the shmget() calls to use 0600 (user r/w).

Tested with legacy Xlib driver and llvmpipe.

anv: Emit a NULL vertex for zero base_vertex/instance

If both are zero (the common case), we can emit a null vertex buffer
rather than emitting a vertex buffer with zeros in it.  The packing of
the VERTEX_BUFFER_STATE is faster because no relocation is emitted and
we can avoid creating the vertex buffer which means one less
anv_state_stream_alloc.

anv: Use an anv_state for the next binding table

This is a bit more natural because we're already getting an anv_state
most places in the pipeline.  The important part here, however, is that
we're no longer calling anv_block_pool_map on every alloc_binding_table
call.  While it's probably pretty cheap, it is potentially a linear walk
over the list of BOs and it was showing up in profiles.

anv: More carefully dirty state in BindPipeline

Instead of blindly dirtying descriptors and push constants the moment we
see a pipeline change, check to see if it actually changes the bind
layout or push constant layout.  This doubles the runtime performance of
one CPU-limited example running with the Dawn WebGPU implementation when
running on my laptop.

NOTE: This effectively reverts beca63c6c07.  While it was a nice
optimization, it was based on prog_data and we can't do that anymore
once we start allowing the same binding table to be used with multiple
different pipelines.

anv: More carefully dirty state in BindDescriptorSets

Instead of dirtying all graphics or all compute based on binding point,
we're now much more careful.  We first check to see if the actual
descriptor set changed and then only dirty the stages used by that
descriptor set.  For dynamic offsets, we keep a bitfield per-stage of
which offsets are actually used in that stage and we only dirty push
constants and descriptors if that stage has dynamic offsets AND those
offsets actually change.

anv: Use a switch statement for binding table setup

It theoretically could be more efficient but the real point here is that
it's no longer really a matter of dealing with special cases and then
the "real" thing.  The way we're handling binding tables, it's more of a
multi-step process and a switch is more natural.

anv: Rework push constant handling

This substantially reworks both the state setup side of push constant
handling and the pipeline compile side.  The fundamental change here is
that we're no longer respecting the prog_data::param array and instead
are just instructing the back-end compiler to leave the array alone.
This makes the state setup side substantially simpler because we can now
just memcpy the whole block of push constants and don't have to
upload one DWORD at a time.

This also means that we can compute the full push constant layout
up-front and just trust the back-end compiler to not mess with it.
Maybe one day we'll decide that the back-end compiler can do useful
things there again but for now, this is functionally no different from
what we had before this commit and makes the NIR handling cleaner.
